Two of the main points Goreau makes are that the IPCC's window of focus is much too narrow—most of the worst climate effects will be beyond its year window—and its conclusions are so "lowest common denominator" that they are greatly underestimating both the data trends and coming impacts. Try it risk-free for 30 days. Among other things, they sold their soul when they colluded with Republicans to change election rules in a way that de facto excludes valid third-party candidates from the process, ensuring the Democrat-Republican duopoly.
